Northern Ireland manager Michael O'Neill has given his players detailed information about their opposition

"The structure Michael has put in place has taken time and effort but we're now set on a process that we believe gives the players the best chance of success."

O'Neill and his staff have watched all the qualifying games of their Group C opponents, with MacPhee tasked with compiling detailed video dossiers.

"There are different ways you can deal with a world class player," said MacPhee.

"You can deal with him in the structure of your team or you can deal with him in a more individual man marking sense."

"Alternatively you can identify the source and look at the service he gets, how he scores his goals and when he scores his goals. This is all information we know and ultimately Michael will make the decision. Over the last two years he's made a lot of really good decisions in the biggest games and got it right time and time again."

Meticulous preparation is a key strength of O'Neill and his team. Players are left in no doubt what their role is, both individually and collectively.
